A long-plate ECC83 / 12AX7A in the tradition of the famous Telefunken ECC803S.

1dB less gain than the RT003 (ECC83-Cz) but very detailed and defined, close to the RT001 (12AX7A),

Its strong cathode current makes it an ideal choice for the audio driver stage as well as for HiFi applications.

Customer evaluation for "ECC803 S TAD Premium Selected"

From: David On: 6 May 2023

Validated !

Best "new tubes" i have tried so far for my Pro-ject phono pre-amp.
Less colored than the expensiver "Psvane art" and more quiet.
Very nice soundstage, the basses are deeper and more detailled.
I can recommend these tubes in a phono preamp with an high end turntable and a good MC cartridge.

From: DIVAIS Jesse On: 12 Nov 2021

Le top !

Ce tube est tout simplement incroyable.
Certains appellent cela 'la vérité sonore', pour celui-ci le terme n'est pas exagéré.
Je le recommande 'chaudement'.

(translated) This hit is simply incredible. Some call it 'sonic truth', for this one the term is not an exaggeration. I recommend it 'highly'. Jesse from the Blue Forum.

From: Jimmy Smithers On: 24 Feb 2013

These tubes deliver tremendous harmonic richness and overtones.While still remaining well defined in all frequences.

Kinda like the "jack of all frequences" tube.

Definateley don't forget sweetness as well.

From: Andreas Leith On: 23 Sep 2009

Weighty, solid, superbly crafted tubes that replaced chinese no-names in my pre-amp, driving class A SE amps.

In conjunction with their 12AX7´s, the immediately apparent changes were a de-fogged, more spatially present and in your face sound.

More detailed yet smoother presentation. Airy... .

Prior edginess on high frequencies have also dissapeared.

Vocals to die for...have substance now...P´s, T´s and S´s -especially on female vocals- are clearly contoured now, liquid and..."juicy(?)".

Who cares...I love´em !

Oh...did I mention that these guys ship and deliver within 36hrs ?!?!

Will definitely shop again !

Information about TAD Matching

Here you will find the most important information about the matching of our tubes

When does a tube become a Premium Selected tube?

Power tubes

All power tubes labeled Premium Selected have passed the following tests:

- Plate Current (PC) and Amplification (TC)

- Low Noise Test

- Microphonic Test

- Sonic Tests

- Shock Tests

- Listening Tests

- Shorts & Leakage Tests

Premium RT-Matching of Power Tubes

Our Premium Matching is an exact matching of power tubes with identical Plate Current (PC) and Transconductance (TC).

TAD Premium Selected tubes are guaranteed for a period of 6 months (according to terms of warranties)

for the quality criteria mentioned above.

Preamp tubes

All preamp tubes labeled Premium Selected have passed the following tests:

- Low Noise Test

- Microphonic Test

- Gain Test

- Sonic Tests

- Shock Tests

- Listening Tests

- Balanced Output Test

Premium Selected

We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.

For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection

HIGHGRADE SELECTION

But only those tubes which pass these tests best are labeled Highgrades.Typically this is approx. 3-10% from a production batch that qualifies for the HIGHGRADE rating from TAD.

Due to the very high selection requirements, this article is temporarily only available to a limited extent! Please note our shop-information on availability.

Matching and Selecting Options for Preamp Tubes

Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.

This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.

TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties)

for the quality criteria mentioned above.
